Although the Russos Q&A did not bring an Avengers 4 trailer, we have now finally gotten a name and trailer for Avengers: Endgame. It teases many of the developments in the upcoming film, which now has a new, sooner release date in the US. The original story follows.

Avengers 4 is already among the most anticipated movies of 2019, promising to resolve not just the cliffhanger left by Infinity War, but the entire last decade of Marvel films. The public hasn't even seen a trailer yet, but there's reason to believe that may change soon.

The ArcLight Hollywood is hosting a special screening of the film tomorrow evening, November 28, which will be followed by a Q&A from the co-directors, the Russo brothers. The original Infinity War trailer premiered on November 29. Marvel is publishing a "Prelude" comic on December 5, before which we expect the title of Avengers 4 to be revealed. Plus we already know that the Avengers 4 trailer is coming sometime this year.

Putting all the pieces together, it seems reasonably likely that tomorrow's ArcLight event will premiere the trailer to the small audience in attendance. Then, the full trailer could drop on the Internet later in the evening or the following day--the one-year anniversary of the last trailer. And it would pave the way for the title reveal in time for the comic.

The title for Avengers 4 has been kept under wraps, though the Russos have dropped cryptic hints. So far the most likely one appears to be Avengers: End Game, a reference to a line (and major plot point) from Doctor Strange in Infinity War.

We expect Avengers 4 to conclude the Thanos arc of the Marvel Cinematic Universe. First teased in a post-credits sequence in the original Avengers film, Thanos has not interacted with the MCU heroes directly until Infinity War. In that film his full plan for the Infinity Gauntlet was revealed: to obtain the power to snuff out all life in the galaxy by sheer will and a snap of his fingers. The resulting events killed off lots of well-established characters in the MCU, leaving a cliffhanger ending for Avengers 4.

Before it comes, though, we'll be getting a dose of reinforcements. In a post-credits sequence in Infinity War, Nick Fury calls in one last contingency plan: Captain Marvel. The implication is that she'll be the heroes' trump card, and we'll see exactly why--and where she's been all this time--in her own standalone movie on March 8, 2019. Avengers 4 will follow on May 3.
